METHOD FOR SEPARATION OF COLLECTORS IN WELL CUTS

摘要

Method for separation of collectors in cuts of wells includes probe lifting and continuous measurement of current values of potential difference for spontaneous polarization, determination of value of respective potential difference of spontaneous polarization by value of which collectors are separated. One performs continuous measurement of current values of potential gradient of spontaneous polarization at probe lifting with determination of respective difference of potential gradient of spontaneous polarization by value of which one separates collectors, with writing and storing maximal and minimal values of potential gradients of spontaneous polarization at probe lowering. At probe lifting simultaneously with measurement of current values of potential gradient of spontaneous polarization one carries out calculation of its respective difference of potential gradient, determination of diffusion spontaneous polarization through measurement of gradients PS at two different values of specific resistance of drill solution (replacement of solution).
